FoCaL Folding Category List CSS Issues

Great Plugin but can’t seem to be utilizing all its greatness on my theme.

#1: the explorer style theme, i can’t quite figure out how to implement it for my category list or how to implement css for this plugin. Is there anyone with a sample css I could work with? I can’t find one one the plugin homepage

#2: When I have a second FoCal List and it is displaying post counts for some reason it is not displaying brackets around the numbers like the initial.
